Hi Pedro,
I'm running aarch64 FS so it's definitely possible (although I am on an
older patch...). I can't really comment on your error except for the
fact that this looks like a memory mapping issue. It could be worth
looking at the patch history to see if something changed recently, just
to check (like searching for "kernel").
Things you could try :
- Only set 'system.highest_el_is_64 = True' and see what happens.
- Older disk image
(http://dist.gem5.org/dist/current/arm/disks/aarch64-ubuntu-trusty-headless.img.bz2)
Hope it works out,
Arthur

Hi all,
I've been recently advised to try full-system instead of syscall emulation due
to some errors I was having with the latter.
Since I never ran gem5 + full-system before I want to do the simplest thing
possible: boot and exit. However, I'm getting errors as displayed below.
To "reproduce" my errors, here's what I've done:
1) clone gem5 2373934b8224e33c55ce96a0fe7751caeee13baf (v20.1.0.4)
2) build gem5
scons build/ARM/gem5.opt
3) build m5
scons -C util/m5 build/aarch64/out/m5
4) build term (to attach and read boot output)
$ cd gem5/util/term
$ make
5) Download recommended guest binaries
(https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries),
namely:
http://dist.gem5.org/dist/current/arm/aarch-system-201901106.tar.bz2
http://dist.gem5.org/dist/current/arm/disks/ubuntu-18.04-arm64-docker.img.bz2
6) Run full system (fs.py) pointing out the disk image, kernel, and bootloader
./build/ARM/gem5.opt configs/example/fs.py
--disk-image=/home/pedro/Projects/gem5/fs_files/ubuntu-18.04-arm64-docker.img

Alternatively, instead of pointing all flags, I exported the M5_PATH to point
/home/pedro/Projects/gem5/fs_files/aarch-system-201901106, and run gem5 again
indicating only the --disk-image. Same error.
7) Found this suggestion of adding the --bare-metal option in a previously

8) Further discussion on previous question also suggest adding --param
'system.highest_el_is_64 = True' --param 'system.auto_reset_addr_64 = True' to
aarch64, which also does not work with:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "build/ARM/python/m5/main.py", line 457, in main
exec(filecode, scope)
File "configs/example/fs.py", line 386, in <module>
Simulation.run(options, root, test_sys, FutureClass)
File "/home/pedro/Projects/gem5/configs/common/Simulation.py", line

raise SimObjectCliWrapperException(
m5.SimObject.SimObjectCliWrapperException: tried to set or access
non-existentobject parameter: auto_reset_addr_64
So... the questions:
- Is it possible to run fs with aarch64? (I suppose so since there are guest
binaries for that)
- Any reason why I'm not able to boot?
Thank you very much for any suggestions!
Cheers,
Pedro.
